SNA Server Event 38, Qualifier 0004 and 0005 Not Documented

MORE INFORMATION

Event 38: APPC session deactivated abnormally

Qualifier:

0002 = The session was deactivated because of a temporary (retry) error,
       and may be retried.

       CAUSE: This can occur when the SNA Server connection to the remote
       system has been lost.

       ACTION: Look for an Event 23 error and check it's qualifier code.
       The SNA Server Reference Guide lists the possible qualifier codes
       and likely causes. For an 802.2 link, qualifier AE and AF indicate
       timeout (or possible media or bridge/router problems) on your LAN
       and will require a LAN trace to diagnose, along with your SNA Server
       configuration file. Pass this information to Microsoft support
       personnel.

0003 = The session was deactivated because of a permanent (no retry)
       error, such as a parameter mismatch. Contact the administrator of
       the partner LUs system to determine which parameters are mismatched.

       CAUSE: A configuration mismatch exists between SNA Server and the
       remote system, or the remote system's session has been reset while
       the SNA Server's conversation remained active.

       ACTION: Capture an SNA Server data link control (DLC) and LU6.2
       message trace of the problem. Pass these traces along with your
       SNA Server configuration file and your Windows NT application event
       log to Microsoft support personnel.

0004 = SNA Server unbound the session due to a protocol violation by the
       partner LU.

       CAUSE: SNA Server detected a protocol violation from the remote
       system on the session.

       ACTION: Capture an SNA Server data link control (DLC) and LU6.2
       message trace of the problem and provide to Microsoft support
       personnel.

0005 = SNA Server sent an UNBIND(Cleanup) message on this session to
       the remote system in order to clean up the session.

       CAUSE: This can be caused by any one of the following:

       1. The SNA Server client machine (where the 5250
          emulator or APPC/CPIC application is running) has
          lost it's network session to the SNA Server.

       2. The 5250 emulator or APPC/CPIC application issued 
          a TP_ENDED(HARD) to cause the LU6.2 session to be
          ended.

       3. The 5250 emulator or APPC/CPIC application failed
          abnormally or was ended by the user while in the 
          middle of a conversation.

       ACTION: If a 5250 user is losing their emulation session
       unexpectedly (due to the client's network session being lost to the
       SNA Server), capture SNA Server client internal trace, LU6.2 message
       trace and APPC API trace of the problem, along with a matching
       sniffer or network monitor trace showing the lost network session
       and provide to Microsoft support personnel.
